ICE December cotton settled 1.44% higher at 78.88 cents/lb on the first trading day of October, but that single-session gain obscures a more telling fact: the contract fell 4.6% for the week, marking one of its sharpest weekly declines in recent memory. The divergence between the daily bounce and the weekly rout captures the core tension in the cotton market—weather-driven supply concerns are colliding with persistently weak demand.
Weather Premium vs. Demand Discount
US cotton belts experienced heavy rainfall this week, with more expected. The timing is critical: bolls are opening, and exposed lint soaked by rain is almost certain to suffer quality downgrades. Severe thunderstorms and high winds could also cause yield losses. From a supply chain perspective, this means grade discounts for US cotton may widen in coming weeks, and premiums for high-grade cotton could strengthen further.
Yet the weather premium failed to reverse the futures slide. Bailey McHenry, a risk management consultant at StoneX, noted the market is in a clear downtrend, and rain-related concerns are merely a brief interruption. The logic is that demand-side pressure is far more persistent than supply-side disruption.
The latest USDA export sales report confirms this worry. For the week ending September 24, current-crop upland cotton net sales reached 202,567 bales, down 12% from the prior week. More notably, net sales to China were just 38,370 bales, while next-crop net sales to China stood at zero. Shipments were equally lackluster: upland cotton export shipments totaled 149,507 bales, down 9% week-on-week, with only 1,323 bales shipped to China.
Oil and Currency Double Squeeze
The G7 agreed to release 100 million barrels of diesel and crude from emergency reserves, with action starting immediately and lasting four months. Oil prices fell on the news, with European diesel futures dropping over 4%. The impact on cotton is not indirect—cheaper oil makes polyester, the most direct substitute for cotton in textile raw materials, more affordable.
When polyester prices decline, the substitution window opens for spinners and fabric mills. For factories heavily reliant on cotton, this means procurement strategies need reassessment: when cotton prices are elevated and quality risks are rising, technical adjustments to blend ratios can be an effective cost-control tool.
On currencies, the US dollar index fell, which should support dollar-denominated commodities, but the combination of rising equities and falling oil meant capital did not flow into cotton futures. The Cotlook A Index stood at 88.35 cents/lb, down 80 points, with the spot market under similar pressure.
Real Impact on the Supply Chain
From a global trade flow perspective, the cliff-like decline in US cotton exports to China deserves scrutiny. Current-crop net sales to China were 38,370 bales, next-crop sales were zero, and shipments were just over a thousand bales. Behind this data lies not only China's reserve rotation and import quota policies but also deeper shifts in Sino-US textile trade flows.
For domestic textile enterprises, rising quality risks for US cotton have two direct consequences. First, the delivered cost of high-grade US cotton may rise rather than fall, as quality premiums partially offset the benefits of lower futures. Second, if rain persists and production cuts are confirmed, the global cotton supply-demand balance sheet will be revised, and the internal-external cotton price spread could widen again.
On a longer horizon, the current weakness in cotton prices is not an isolated event. Global textile and apparel consumption recovery is falling short of expectations, and brands and retailers are still digesting inventory, keeping raw material procurement at a hand-to-mouth pace. This demand-side restraint makes it difficult for any supply-side weather story to sustain a rally.
